I've never given it thought before or checked, but to what extent does the load and speed indexes matter when it comes to performance/handling but more importantly MOT/insurance, if at all?
Do your car manuals advise on any minimum and recommended values in each case?
In my case, just been looking at replacement tyres for the Celica and noticed that for 205/45/17, CSC3 are either £115 a corner for 88W or £99 for 84V. From Blackcircle, the difference is max top speed of 168mph(W) vs 149mph(V) and 560kg(88) vs 500kg(84). Speed is well within limits for non-track use and you'd only really hit 2 tons in the car, if you had 4 obese people in there and the boot equally filled.
My manual doesn't advise any minimums but its recommended tyre pressures are based on the 88W.
Does everyone stick religiously to the numbers?
